Problem with Ram

[phentona158602da]

Hello all, i want to upgrade my ram to 64gb, but to times my ram doesnt work, there is an E8 error.
Previous Ram works fine.
I am very confused
The ram that i bought is
G.Skill Trident Z 64GB DDR4 64GTZ K4 3200 C16

My motherboard is:
X299 GAMING PRO CARBON

and cpu
Intel(R) Core(TM) i7-7800X CPU @ 3.50GHz 3.50 GHz

It will be very heplful, if you could answer, because i am about to sent the ram back

Also different sites say that the motherboards capicity depending of the cpu chipset, so others say 64, others 128, others 256.

I tried reseting csmos, also activate deactivate xmp.

Thanks alot.

Please list exactly the model of your old RAM and your new RAM. Example for the G.Skill: F4-3200C16D-64GTZR (not sure this is your model).
Look at the package of the kit or at your order confirmation.

You have an X299, which is a quad-channel board, with a quad-channel-capable CPU. So i will already leave this here for you to read while you look up the RAM, some of it might also apply to you:

My new ram is G.Skill: F4-3200C16Q-64GTZ
My old ones are 2 G.Skill F4-3200C16-8GVKB
and 2 Corsair CMK16GX4M2B3000C15

I know that i mixed rams.

Then you know why this is a problem...

The new RAM, does it work on its own, if you use just those four modules in the appropriate slots (A1+B1+C1+D1)?

 

[phentona158602da]

no
also they are in the list of msi support,

I will not use any more the other ram

 

[phentona158602da]

So, i did update of the BIOS, but now only 32 of 64 are recognized

 

[phentona158602da]

So, for some reason one module wasnt recoqnized in the first slot, but on others was, so i changed the rams in slots, now everything works, if you think that this will cause me problem later, please tell me

 

[citay]

So now you got only the new kit of RAM in slots A1+B1+C1+D1, all are detected and you have the full 64 GB total capacity shown? That is good.

Now run this: Memtest86 Free from https://www.memtest86.com/
Launch the included ImageUSB program to prepare a USB drive with it, then boot from that drive (press F11 during POST for the boot menu).

The test takes some time. I want to ask you, I want to upgrade to 128, should I buy, again 4 for the same ram? Or I have to buy 4x32? And also what happens ramwise and the motherboard if I buy a new CPU with newer chipset, how they are depending?

You can buy this exact kit of RAM again, but it might be harder to get after a couple of years. Also, you will then be stressing the CPU's memory controller more, which could cause slight problems at DDR4-3200 and you might have to lower the frequency a bit. This depends on your individual CPU, it's also possible that it will all run fine. But given your slight problems with four modules already, i can't guarantee anything for eight modules. Might work fine, might not. The 32 GB modules have their own challenges. Often times they have quite bad XMP timings. So you might wanna first try with the 8x 16 GB.

As for the RAM in a new system: Well, it depends mainly on the new platform's memory system, dual-channel vs. quad-channel. Which hardware would you possibly buy later?

 

[phentona158602da]

I thought this one
Intel Core i9-10940X 3.3 GHz 14-Core Processor

And after some time change motherboard also
Not all at once

But that's from the same Skylake generation, so it would have to be another X299 board. Not much of an upgrade. I think Intel pretty much said goodbye to the HEDT market, not much activity from them in recent times. Not that AMD does much on the Threadripper side anymore either.

Instead of spending more money on that old platform, it would be more beneficial to switch to a normal Z690 DDR4 + i9-12900K for example. Much lower platform costs, but should still beat even the i9-7960X in performance. I can't find a direct comparison right now, but those CPUs are fast. Previously you could only get that performance on a workstation platform, now it's on a desktop platform.
